Abstract (en)
[origin: WO2005121043A1] The invention relates to a base composition for producing shaped refractory objects based on SiC, to the method using said composition, to the moulded product obtained with a high SiC content, and to the use of one such product, especially for constructing electrolytic tanks used in the production of aluminium. The inventive composition is characterised in that it contains, in weight: at least 2 % of a metallic silicon powder having a particle size less than or equal to 10 ñm; at least 3 % of a metallic aluminium powder; and at least 85 % of a silicon carbide powder SiC; the sum of said three constituents representing 100 %, the maximum total content of possible impurities amounting to 0.5 wt. %.
